55

$200–$2,000/day

A single broken mobile checkout costs the average mid-size Shopify store this much, every day it stays broken.

Every bug ships with an AI root cause and a copy-paste CSS or Liquid snippet. Most are resolved in under 10 minutes.

Theme Change Shield

Auto-scan every time you publish a theme

BugSense listens for Shopify theme publishes. The second you (or your developer, or a third-party app) ship a change, we kick off a full scan and alert you on Slack, Teams, or email if a new high-severity bug just shipped to customers.

  • Scan completes in 60–90 seconds — usually faster than the cache invalidates
  • Compares against the last clean scan to surface only what the publish broke
  • One-click rollback link straight to the previous theme version

Frequently asked

Does BugSense modify my theme?+

No. BugSense requests read-only access to your theme files for analysis. It never writes to your store, modifies your theme, or affects your storefront in any way.

How fast can I get value out of it?+

Install + first scan completes in under 3 minutes. Most merchants find at least one revenue-impacting bug in the first 24 hours.

What does it cost?+

Every plan starts with a 7-day free trial. Shopify-billed merchants pay nothing upfront. Cancel from Shopify Admin and the charge is voided. Pricing tiers and scan limits are on the App Store listing.

Can I install on a development store?+

Yes. Connect any store, including development stores. Scans run against the live storefront URL, so the theme needs to be published to see results.

How is this different from a generic uptime monitor?+

Uptime monitors check whether the server returns 200. They miss every silent failure: broken Add-to-Cart, mobile layout shifts, missing product images, checkout flow errors after an app update. BugSense renders the actual page on real viewports and flags the visual and functional bugs uptime tools cannot see.
